I can see that you are extremely sloppy, re-using the comments from the
first part without a thought. Your signature sucks, too.

A quality response as usual Lars.
Why do you even bother?

see http://mindprod.com/jgloss/javacexe.html for how to compile
see http://mindprod.com/jgloss/javaexe.html for how to run

The output will be what you desire.

see http://mindprod.com/jgloss/jdk.html
if you don't have a jdk installed yet.

Please embed your question in the body of the post, not just the title. 

Question: "Can someone determine the output of this?"

Since this is a 'float' expression, you should express the constant as a float.

This is not subtraction of 32:
> 		cel = cel*9;

> 		// Divide the answer by 9

This is not division by 9:
> 		cel = cel/5;

> 		// Multiply that answer by 5

This is not multiplication by 5:

Yes.
